A measuring device, intended for measurements on whole blood, comprises a sample fluid chamber for containing a blood sample, ion-selective potentiometric electrodes for measurement of the concentrations of sodium and potassium ions, a reference potentiometric electrode, an optical sensor for measur ...

The present invention relates to an enzyme sensor for measuring the concentration or activity of an analyte in a test fluid. The sensor has at least one enzyme layer comprising an immobilized enzyme for which the analyte is a substrate. The immobilized enzyme is obtained by formation of one or more ...

A compact electrochemical measuring electrode device (1) constructed in thick film technique on a plane circular substrate (13) of a ceramic material such as alumina, the electrodes (14, 15) of the electrode device being arranged on one side of the substrate, and the electrical connections (20, 26, ...

An automatic blood sample analyzer for automatically measuring one or more unknown data or parameters of the blood samples, such as partial pressure of carbon dioxide, partial pressure of oxygen, the pH-value, and the hemoglobin concentration, and the analyzer comprises computer means for calculatin ...

The sensor (1) comprises a sensor body (3) thermostatable by means of a first thermostating system (14,15) and having an outer surface (3a,40a) for application to the human body (28) in heat conductive relationship therewith, said outer surface (3a,40a) forming the measuring surface of the sensor (1 ...

A method of photometric in vitro determination of at least one blood gas parameter in a sample of whole blood. The whole blood sample is obtained by connecting an at least partially transparent sample container to an in vivo locality and transferring whole blood into the sample container, then break ...

Method and apparatus for spectrophotometrically determining the concentration of a number of hemoglobin derivatives comprising at least deoxyhemoglobin and oxyhemoglobin or parameters derived from the concentration of individual hemoglobin derivatives, in particular the oxygen saturation fraction, i ...

A package containing a reference liquid for the calibration and/or quality control of blood gas analyzers. The reference liquid is enclosed in a flexible, gas-tight container without any gas bubbles in the container, and to avoid any danger of formation of gas bubbles, the total gas pressure in the ...

The concentration of molecular oxygen in a sample is determined by exciting oxygen molecules of the sample from the electronic ground state to the excited .sup.1 .DELTA..sub.g state (excited singlet state), measuring a 1270-nm luminescence characteristic of the excited oxygen molecules (singlet oxyg ...
